KK-B1700 is a 1.70m diameter floating buoy for near-shore ports, coastal and inland waterway applications. The buoy body is made of high molecular PE.
1. Full PE design and closed-cell PE foam filling
2. The floating part is made of 316 stainless steel rods to increase strength
3. The middle section has a larger secondary battery housing available

Easy to deploy
Three rotational molded parts are provided for easy deployment and maintenance
Color
Dark yellow, marine warning color
Buoyancy and stability
The buoy part is filled with closed-cell PE foam, which provides excellent buoyancy and helps keep the buoy upright in the event of a ship collision
Durable
Two large lifting and mooring points are interconnecte d by 316 stainless steel rods, providing high strength
Cost-effective
PE material inhibits the growth of marine plankton, reducing the need for buoy cleaning, and the frequency of cleaning is lower than that of steel buoys. And low maintenance cost.

Yantai Kekan Ocean Technology Co., Ltd. is a technology-based small and medium-sized enterprise that integrates the researchand production of marine observation and monitoring equipment, marine environmental services,and the development of key supporting systems for marine engineering. Adhering to the spirit of "scientfic management and exploration of the deep sea", it focuses on the research and development of intelligent marine observation and monitoring equipment and the safety guarantee of offshore engineering.
The R&D team of the company is led by Professor You Zajin, an academician of the European Academy of Sciences. He has been engaged in research on ocean dynamics, numerical model construction,and has led projects funded by the Natonal Young Scholars Fund, the Ministry of Sclence and Technology's key R&D project, the National Key Fund, and multiple Australian Key Fund projects.The core personnel of the team also include multiple doctoral and high-end managemert talents in the marine field, with complementary professional backgrounds and a solid foundation for cooperation. They have jointy cariedout muliple related projects/research projects and possess the strength of product design, manufacturing, and sales. Since its establishment, the company has applied for more than 30 patents and softworks, of which 13 have been authorized, possessing exclusive intellectual property rights and strong technical barriers.
The company's main products are intelligent marine environmental element observation and monitoring equipment and high-precision early warning and forecasting system, among which the intelligent observation and monitoring equipment has the function of self-positioning, which can adjust the positioning based on real-time sea conditions and relying on low-power power system; The submarine winch has the advantages of small size, strong traction and good sealing, which can better adapt to the complexity of the seabed work; The high-precision marine hydrological element early warning and prediction system provides wave, tide, storm surge and sediment transport data, solves the problems of unclear physical mechanism and low simulation accuracy of current numerical simulaton, and can provide a solid guarantee for marine enginering.
Kekan Ocean is a creative and dynamic team. We are committed to providing more users at home and abroad with the best quality products and services.
